Borosilicate glass is a type of glass composed primarily of silicon dioxide and sodium borate. What sets it apart from other types of glass is its specific chemical composition, which includes a higher proportion of boron oxide. This characteristic gives borosilicate glass unique properties such as its thermal resistance and exceptional durability.
Borosilicate glass is able to withstand high temperatures without breaking. This makes it an ideal material for tableware such as teapots or cups.
Thanks to its molecular structure reinforced by the presence of sodium borate, borosilicate glass is more resistant to shocks and scratches than ordinary glass.
This glass offers exceptional transparency.
Available in different forms, borosilicate glass can be found in our GUSTAVE teapots and herbal teapots, our HELYA single or double-walled cups, our YCARE infuser and our OCTAVE coffee makers.
